Title: Improvements relating to the winding of yarns and threads
IPC: B65H55/04
Filed: 1936-02-08
Abstract: 456,799. Winding yarns &c. ABBOTT MACHINE CO., Wilton, New Hampshire, U.S.A.-(Assignees of Abbott, E. J.) Feb. 8, 1936, Nos. 3925 and 3926. Convention dates, Feb. 9, 1935 and Feb. 4, 1936. [Classes 120 (ii) and 120 (iii)] A yarn or thread package is formed by winding the main portion in layers having a slow spool-wind traverse and, between the operations of winding successive layers of the main portion of the package, giving the yarn a number of quick cross-wind traverses in a zone at an end of the main portion of the package ; the quick cross-wind traverses may be given at both ends of the package and the end zone or zones may be caused to grow in diameter in uniformity with the growth in diameter of the main portion of the package so that the peripheral surface of the fully wound package is cylindrical or conical. As shown in Fig. 1, zones 14, 16, of quicktraverse cross wound windings 13, 17 are arranged at each end of the main body 15 of slow spool-wound windings. A machine for winding the package has a traverse bar 37, Fig. 2, slowly reciprocated for winding the main body of the package and at the end of each stroke of the bar 37, the yarn is picked up by grooves in the roll 33 driving the package and quickly traversed a number of times to form the cross-wound windings ; the traverse bar may be replaced by a slowly rotating grooved roller which may have grooves such as described in Specification 339,679, [Class 120 (ii)]. In another machine the traverse bar is connected to a carriage which is slowly reciprocated to form the main body of the package and the carriage houses a grooved cam engaging a follower on the traverse bar ; the cam comprises an electric motor which, with the cam, does not rotate during the winding of the main body of the package but as the carriage approaches the ends of its traverse, contacts thereon engage fixed contacts to complete a circuit through the motor which, with the cam, is then driven to reciprocate the traverse bar quickly at the end zones of the package. In a further form, the slowlyreciprocating traverse bar carries a rotatable quick-traverse cam having tapered tyres at its ends which, at the ends of the traverse of the bar, engage, and are driven by, enlarged tapered portions on the package-driving roll; the cam driving the traverse-bar is formed to provide a slight dwell at the end of each stroke of the bar.

Title: Improvements in or relating to can-openers
IPC: B67B7/46
Filed: 1951-02-26
Abstract: 697,635. Can-openers. FROST, E. Jan. 10, 1952 (Feb. 26, 1951], No. 4617/51. Class 66 A can-opener of the. type wherein a hook or equivalent abutment at the front of the tool engages beneath the rim at the outside wall of the can and serves as a fulcrum for a lever arm extending rearwards in the form of a handle, there being dependent from the lower edge of the lever arm at its forward end a blade adapted in use to pass inside the rim of the can and shear through its top, and wherein the process of opening the can is carried out by a succession of rocking movements of the tool, is provided with means to limit the forward movement of the tool in each successive step in its operation. In the embodiment of Figs. 1 and 2 a handle 1 carries an abutment 4 and has a cutting edge 7 with a claw-shaped piercing part 5. The abutment 4 is engaged beneath the rim of the can and the handle 1 is depressed so that part 5 pierces the can and then subsequent depression causes the edge 7 to shear the top close to the rim. On lifting the handle 1 and moving the tool forward in readiness for the next cutting depression the claw 5 engages the forward end of the incision made by edge 7 and limits the forward movement of the tool. In the alternative embodiment of Figs. 11 and 12 the abutment 20 and cutting edge 16 are carried on separate lever handles 11 and 12 pivoted together at 13. Two lugs 21 on the lever 12 limit the relative movement of lever 11 which can be moved to position the edge 16 and piercing point 15 above abutment 20 and behind the forward lug 21 for initial application of the tool to a can, whereupon levers 11 and 12 are pressed into alignment causing point 15 to pierce the top of the can which is then opened by successive rocking and forward movements of the tool using levers 11 and 12 as a single handle. The rear lug 21 engages the rim of the can at the end of each cutting stroke and the handle is then raised with a forward pressure so that the tool slides forward on edge 16 over the uncut portion of the top of the can until the forward lug 21 strikes the can rim, the tip of claw 15 being still within the cut preventing excessive forward movement.

Abstract: 667,466. Separation of gases. ELLIOTT CO. Feb. 23, 1950 [March 15, 1949], No. 4660/50. Class 8 (ii) A method of separating methane, hydrogen and a constituent having an intermediate boiling point e.g., a mixture of nitrogen and carbon monoxide from a ternary mixture, e.g. coke oven gas, comprises compressing the mixture at a compressor c, cooling in at least three stages e.g., heat exchangers 2, 4, 8 to liquefy all but the hydrogen, using the resulting liquefied constituents in a condenser 26 to condense liquid reflux for rectifying in a column 6 said liquefied constituent to obtain substantially pure liquid methane and gaseous intermediate constitutent, expanding to atmospheric pressure at a valve 42 this latter constituent and passing it through the exchanger 2, using the liquid methane to cool the exchanger 4 and to act as reflux in the column 6, and using the hydrogen as a cooling agent in all stages but the second, i.e. exchanger 4. Hydrogen gas at 97 per cent purity and waste mixture of carbon monoxide and nitrogen are delivered through ducts 18, 23 and liquid methane from the base of the column 6 traverses a cooler 28, is expanded to one atmosphere at a valve 33 and is fed into a storage tank 34. The exchanger 8 serves as a liquefier and residual hydrogen is purified in a liquefier 12 and a liquid collector 13, the gas from which is expanded at a turbine 16 and traverses the liquefiers 12, 8 and the exchanger 2. Auxiliary cooling of the liquefier 8 is effected by an external refrigerating circuit wherein waste mixture of carbon monoxide and nitrogen is forced by a compressor 52 through an aftercooler 53, a heat exchanger 54, an expansion turbine 57 and the liquefier 8. In a modification the liquid methane from the column 6 is expanded to one atmosphere and serves to cool two extra heat exchangers and also the exchanger 2 before being delivered as gas.
